Resin tower processing capacity calculation method

This post was last edited by sunjl1981 at 2013-1-6 23:32 Dear brothers and seniors, please ask for urgent help on the caustic soda resin tower processing capacity calculation method#, , &
It is necessary to know the ion exchange capacity of the resin used, the diameter of the resin tower, the height of the resin filling, the calcium and magnesium indicators of the primary brine, the operating mode of the resin tower and other data and information. Give an example: c467, calcium 0.25eq/l-resin, d1800, 141cm, calcium + magnesium
What is 0.785? Is it the exchange capacity of the resin? What is CR----11? We have a two-tower process with 24-hour switching and single-tower regeneration for 6 hours. The diameter is also d1800. How to calculate it? Calcium + magnesium
0.785=3.14/4 (1) Resin volume = 3.14 × (1.8/2) 2 × resin filling height (m) m3 (2) Q (brine flow) m3 /h = resin volume × 1000 × 0.25 × 40/10 × 2 × 24 Calcium 0.25eq/l-resin (penetration amount: 0.02ppm) This is a three-tower process.
Can the teacher explain it in detail? Why is the calculation of Q divided by 10 2 24. Shouldn't the volume calculation of resin be calculated by multiplying the radius by itself and then multiplying by 3.14 times the height?
0.785* 1.8 * 1.8 * 1.41=3.6 cubic. Shouldn’t the volume calculation of resin be calculated by multiplying the radius by itself and then multiplying by 3.14 and by the height? What does 0.78 mean here? What does 1.8 mean when the diameter is multiplied by itself? 3.6 * 1000 * 0.25 * 40/(10 * 2 * 24) = 75 cubes, times 40 divided by 10 * 2 * Does 24 mean?
c467, calcium 0.25eq/l-resin, d1800, 141cm, calcium + magnesium
The resin tower is designed to operate with one tower and the second tower is used as a protection tower, so the one-tower design
1. I don’t know much about the CR-11’s switching capability. You should check its technical manual. I estimate it is similar to the 467.； 2. Regarding the calculation method, I think it has been written very clearly. Please understand it yourself. If you have any questions, please communicate via text message. 3. The conditions and calculation results in normal production are different. First of all, the total calcium and magnesium content of primary brine is generally less than 1ppm. However, for the sake of insurance period, most units still switch according to the designed time. 4. Thank you for your attention and welcome to communicate.
Multiply 40 divided by 10* 2 * Does 24 mean?
Hello, brother on the 4th floor: Your reply makes sense to me but calcium 0.25eq/l-resin (penetration amount: 0.02ppm) What does the penetration amount in brackets mean? (Penetration amount: Should 0.02ppm) be equal to calcium 0.25eq/l-resin? How should it be calculated? I still don’t understand. I hope you can give me some guidance! ! Thank you very much, brother! !

Please give me some advice from the second floor prawn: your example of formula 3.6* 1000 * 0.25 * 40/(10 * 2 * 24)=75 cubic centimeter, * 40/(10 * 2 * 24) What does it stand for?
“3.6* 1000 * 0.25 * 40/(10 * 2 * 24) = 75 cubic "where: “40" represents the atomic weight of calcium ； “10" represents the total amount of calcium and magnesium in primary brine ； “2" represents the valence of calcium ； “24" means 24 hours ； Is it clear?
